About this tool
Text Compare shows you exactly what changed between two versions of a text. It works on any plain text: code, config files, docs, emails, whatever. Paste the original on the left and the updated version on the right. Added lines show up in green, removed lines in red, and unchanged lines stay neutral. It's handy for spotting accidental edits, reviewing changes before committing, or just double-checking that two strings are actually the same.
